Comment (by mcs):

 Replying to [comment:19 gk]:
 > Alright, I think I have figured out all the pieces involved. The problem
 starts with https://bugzilla.mozilla.org/show_bug.cgi?id=1321528 being
 fixed in https://hg.mozilla.org/releases/mozilla-beta/rev/1c4863a4ff98 AND
 NoScript 2.9.5.2rc3 (commit 9eab569b1d443456325e2b253f2cca65eb453c30 in
 the git repo at https://github.com/avian2/noscript). The whole
 suspend/resume mechanism got introduced there to fix the mediasource
 blocking for us. ;)

 Interesting. NoScript's role is confusing to me. Are you saying that
 NoScript relies on the fix for
 https://bugzilla.mozilla.org/show_bug.cgi?id=1321528 and that the same
 Mozilla fix causes this bug?

 > While I don't have assembled all of the pieces to a coherent picture
 yet, the proposed attached fix seems to be a good idea to me. mcs/brade:
 That one works across different platforms, right? If so, do you think you
 want to propose that one for review?

 No, the fix we proposed does not work on Linux (at least not for us). See
 comment:16.
